Seven suspected members of two triad societies were injured in a fight in Tsim Sha Tsui. A group, thought to be members of the Wo Shing Wo and Sun Yee On gangs, were involved in a brawl outside a karaoke lounge at 4.30am. They fled before police arrived but seven later went to Queen Elizabeth Hospital with chop wounds. Two men, aged 29 and 48, were in a critical condition.
